Chelostoma mocsaryi species group

The four representatives of the Chelostoma mocsaryi species group are characterised in both sexes by the basal area of the propodeum, which is impressed, crossed by rather coarse longitudinal carinae and bordered posteriorly by a raised and polished to imperceivably shagreened transverse ridge (Fig. 55). Additional characters of the females are the medially flat base of the labrum, the absence of a small triangular incision at the apical margin of the labrum (Fig. 52) and the length of the basal area of the propodeum, which is as long as to shorter than the metanotum (Fig. 55). Additional characters of the males are two small tubercles or cone- to tooth-shaped projections on the hypostomal area arising laterally to the hypostomal carinae (Fig. 54, 60, 70), two short and rearwards projecting teeth on tergum 7 below the two upper teeth (Fig. 56, 71), and a well delimited polished to more or less shagreened, impunctate, hairless and sometimes slightly concave zone along the lower margin of the compound eye (Fig. 61). Chelostoma mocsary and probably also the three other species are oligolectic on Ornithogalum ( Asparagaceae).
